| menuconfig LEDS_TRIGGERS |
| bool "LED Trigger support" |
| depends on LEDS_CLASS |
| help |
| This option enables trigger support for the leds class. |
| These triggers allow kernel events to drive the LEDs and can |
| be configured via sysfs. If unsure, say Y. |
| |
| if LEDS_TRIGGERS |
| |
| config LEDS_TRIGGER_TIMER |
| tristate "LED Timer Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled by a programmable timer |
| via sysfs. Some LED hardware can be programmed to start |
| blinking the LED without any further software interaction. |
| For more details read Documentation/leds/leds-class.txt. |
| |
| If unsure, say Y. |
| |
| config LEDS_TRIGGER_ONESHOT |
| tristate "LED One-shot Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to blink in one-shot pulses with parameters |
| controlled via sysfs. It's useful to notify the user on |
| sporadic events, when there are no clear begin and end trap points, |
| or on dense events, where this blinks the LED at constant rate if |
| rearmed continuously. |
| |
| It also shows how to use the led_blink_set_oneshot() function. |
| |
| If unsure, say Y. |
| |
| config LEDS_TRIGGER_IDE_DISK |
| bool "LED IDE Disk Trigger" |
| depends on IDE_GD_ATA |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled by IDE disk activity. |
| If unsure, say Y. |
| |
| config LEDS_TRIGGER_HEARTBEAT |
| tristate "LED Heartbeat Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled by a CPU load average. |
| The flash frequency is a hyperbolic function of the 1-minute |
| load average. |
| If unsure, say Y. |
| |
| config LEDS_TRIGGER_BACKLIGHT |
| tristate "LED backlight Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled as a backlight device: they |
| turn off and on when the display is blanked and unblanked. |
| |
| If unsure, say N. |
| |
| config LEDS_TRIGGER_CPU |
| bool "LED CPU Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled by active CPUs. This shows |
| the active CPUs across an array of LEDs so you can see which |
| CPUs are active on the system at any given moment. |
| |
| If unsure, say N. |
| |
| config LEDS_TRIGGER_GPIO |
| tristate "LED GPIO Trigger" |
| depends on LEDS_TRIGGERS |
| depends on GPIOLIB || COMPILE_TEST |
| help |
| This allows LEDs to be controlled by gpio events. It's good |
| when using gpios as switches and triggering the needed LEDs |
| from there. One use case is n810's keypad LEDs that could |
| be triggered by this trigger when user slides up to show |
| keypad. |
| |
| If unsure, say N. |
| |
| config LEDS_TRIGGER_DEFAULT_ON |
| tristate "LED Default ON Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be initialised in the ON state. |
| If unsure, say Y. |
| |
| comment "iptables trigger is under Netfilter config (LED target)" |
| depends on LEDS_TRIGGERS |
| |
| config LEDS_TRIGGER_TRANSIENT |
| tristate "LED Transient Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows one time activation of a transient state on |
| GPIO/PWM based hardware. |
| If unsure, say Y. |
| |
| config LEDS_TRIGGER_CAMERA |
| tristate "LED Camera Flash/Torch Trigger" |
| depends on LEDS_TRIGGERS |
| help |
| This allows LEDs to be controlled as a camera flash/torch device. |
| This enables direct flash/torch on/off by the driver, kernel space. |
| If unsure, say Y. |
